.png files are intended for web use only, and are not large enough or high enough resolution to be used for print.

Other: .jpg

.jpg files are images and can be used in ways similar to .eps and .png files. .jpg files can be opened using any photo viewer program as well as Photoshop and other design programs. For a .jpg file to be suitable for print, the size of the files needs to be greater than 1MB.

According to CSU graphic standards, if you are using the word mark for your school, department, or other entity, you must also place a CSU/CAS mark somewhere on the piece you are designing. When manipulating the size of any word mark, hold down the shift key so that the proportions remain the same.
